The windy weather is many and the dust is flying, which has a great influence on the light transmittance of the shed film. Especially in the greenhouse near the roadside, there is too much dust, and even the light transmittance of the shed film can be less than 50%. At present, dust strips have become the standard in the main vegetable production areas. However, during the recent interview, the author found that the dust-removing cloth strips on some greenhouses were not properly set, which affected the dust-removing effect.

In autumn and winter, the light time is short and the intensity is weak. The importance of film dust removal in the greenhouse is highlighted. Reasonably set dust-removing cloth strips can remove most of the dust on the shed film and improve the light transmittance of the shed film by more than 30%.
One is to adjust the length of the dust cloth.
Generally speaking, the length of the dust removal cloth strip is 1 ~ 1.5 meters longer than the width of the shed. If it is left too long, there are many overlapping parts between different dust removal cloth strips, it is easy to entangle and form a group, which affects the later dust removal effect . Of course, the setting of the dust removal cloth strip should not be too short, otherwise the range of left and right movement is too small, and the dust removal effect is poor.
The second is to reasonably move the dust removal cloth strip.
The dust removing cloth strip swings left and right with the help of wind force. If fixed up and down, the dust removing cloth strip can only sweep the dust in the middle part, and the upper and lower ends are still covered with dust. Vegetable growers can set up a steel wire at each of the upper and lower ends, tie the cloth strip to the steel wire, and move it once every week or so, to ensure that the whole shed can sweep the dust.
